“平移与旋转”这部分内容,把代数和几何很好的结合在了一起,在整个初中数学中占有极其重要的分量.这部分内容在现代数学、物理学、工程学等学科上面均有广泛的体现,对于学生解决实际问题能力的提高也有着极大的促进作用.本文以人教版初中数学为例,分别从教材内容、教材内容与图形部分其他内容的联系、联系生活实际、直观感受及情境创设五个方面对“平移与旋转”做了深入而细致的教材及教学策略的探析.一、“平移与旋转”教材分析
“Translation and rotation ” This part, the algebra and geometry well together, in the entire junior high school mathematics holds an extremely important component.This part of the content in modern mathematics, physics, engineering and other disciplines are above Has a broad manifestation of the ability to solve practical problems for students also has a significant role in promoting.This article takes PEP junior high school mathematics as an example, respectively from the textbook content, textbook content and graphic part of the other elements of contact, contact life reality, Intuitive experience and situational creation of the “translation and rotation ” made in-depth and detailed textbook and teaching strategy analysis. “Translation and rotation ” textbook analysis
